UNITED STATES PATENT OFFICE 00., OF'NEW YORK, N. Y., A CORPORATION OFNEW YORK ATTACHMENT TO EMBOSSING OR STAMPING MACHINE Application filedDecember 31, 1929. Serial No. 417,638.

My invention relates to a new and useful improvement in embossing orstamping devices. 1

One of the objects of my invention is to provide a simple and usefulattachment, which can be used in connection with machines of the typeshown in U. S. Patent No. 1,730,984 issued October 8th, 1929.

Another object of my invention is to proyide an embossing or stampingdevice which 'will permit the use of separate type members, and whichwill make it -possible to securely hold said separate type members inproper alignment, so as to secure stralght-line stamping.

Another object of my invention is to provide a device of this characterwith a universal clamping device which will make it possible to readilysubstitute type members in the device, so as to print or stamp markingsof varying length.

Other objects of the invention will be set forth in the followingdescription and drawings which illustrate a preferred embodimentthereof, it being understood that the above general statement of theobjects of this invention is intended to generally explain the samewithout limiting it in any manner.

Fig. 1 is a top view showing the clamp in operative position.

Fig. 2 is a front elevation.

Fig. 3 is a sectional view along the line 33 of Fig. 2.

Fig. 4 is a view similar to Fig. 1, but show- 5 ing the clamp in theinoperative position.

Fig. 5 is a detail perspective view of the clamp.

It has heretofore been customary, in many classes of work, to print orstamp by means of separate type members. For example, this work is doneupon leather goods when it is necessary to print or stamp the initialsof the owner.

For many years it has been customary to clamp the aligned type membersby means of a pair of jaws, which were moved towards each other, andaway from each other, alonga line parallel to said type members.However, this clamping often resulted in slightly displacing the typemembers from proper proper alignment, it has been proposed to i use asupplemental clamp, which operated against a piece of metal which waspressed against the type members along a line perpendicular to the lineof printing. However, unless this piece of metal had the exact size, itwould not prevent the type members from being forced out of alignment bythe pressure of the main clamping jaws.' Hence, it was necessary for themanufacturer to keep on hand a large number of these pieces of metal,and the substitution of one of these pieces of metal for another,considerably slowed up the operation of substituting one set of typemembers, for another set. This was particularly objectionable wheninitials were stamped on leather goods for example, be-

cause each set of initials is usually stamped on only one or a fewleather receptacles.

According to my invention, a device of this type is provided with auniversal third clamping member which can be readily manipulated ordetached.

The device which is made of any suitable metal, such as brass, isprovided with a base portion 1, side walls 2 and 2a, and a guide plate3. The parts are connected by rivets or by any other suitable means. Apair of clamping jaws 4 and 4a, whose adjacent faces are planar, arecaused to move towards each other, or away from each other, by means ofthe screw 5, which is mounted in suitable bearings in the members 2 and2a. Said screw 5 is provided with knurled knobs 6 and 6a which areconnected to the projecting ends of the screw 5 by means of collars 7and 7a, held in position by clamping screws 8 and 8a. Hence, the screw 5can freely turn, without any lateral shifting. The jaws 4 and 4a haveoppositely threaded bores, with which the thread of the screw 5cooperates, so that when the screw 5 is turned, the jaws 4 and 4a aregiven relative movement in opposite jaws 4 and 4a also make slidingcontact witlr the wall 9, above and below the guide plate 3, so thatsaid jaws are held in proper alignment at all times. In this particularembodiment, the members 2, 2a, 3 and 9 are integral with each other, butI do not wish to be limited to this integral construction. A plate 10 isconnected to the member 1, and to the guide plate 3, by means of screws11, and a spacin block 12 is provided so that the plate 10 is rmlyclamped by the screws 11,. in

proper position.

A clamping screw 14, provided with a knurled head 15, passes through asuitably threaded openin in the member 10.

As shown in ig. 3'for example, the jaws 4 and 4a are provided with slotsor recesses in which a clamping member 16 is slidably mounted. Thisclamping member 16 is provided with detachable screws 17 and 17a, whichfit into correspondingly threaded openings in the ends of the clampingmember 16. The clamping member 16 is freely slidable with respect to thejaws 4 and 4a, but the heads of the screws 17 and 17 a,are sufiicientlylarge to prevent the clamping member 16 from slipping out of position.

The operation of the device is as follows One or more type members T areplaced in proper position against the wall 9. Either the knob 6 or theknob 6a is turned, to cause the jaws 4 and 4a to lightly clamp the typemembers T. The screw 14 is then manipulated, to force the clampingmember 16, into the position shown in Fig. 1. Irrespective of the widthof the line of type, the clamping member 16 acts immediately to hold thetype members firmly, in proper aligned position. The screw 5 can then beturned to exert additional clamping force against the type members T.

If desired, the screw 14 can be first operated to force the member 16into final clamping position, or into preliminary lightclamping osition,and this feature is of particular va ue when a long line of type isbeing assembled.

It is impossible for the type members to move out of proper alignmentbecause the jaws 4 and 4a do not exert any force upon the clampingmember 16.

In the embodiment herein described as the preferred embodiment of myinvention,

both ends of the clamping member 16 project beyond the jaws which areadjacent to said ends. Likewise, the clamping member is movably mountedin the jaws. However, these details could be varied without departingfrom the invention. For example, if the clamping member 16 were movablymounted on any other part of the device, it would operate according tomy invention as long as it could be moved in a direction perpendicumaryclamping means for clampin the type members T by means of their endaces, andthat the member 16 together with the screw 14, constitutesadditional clamping means adapted to clamp the lateral faces of the typemembers. It will be understood that this description only applies to theparticular position in which the parts have been shown in the drawings,for sake of convenience, and that the invention is not limited to anyparticular position of the parts, shown and described herein. Likewise,it would not be departing from the invention if one of the jaws 4 or 4awere fixed.

I have shown a preferred embodiment of my invention, but it is clearthat numerous changes and omissions can be made without departing fromits spirit.

I claim:

1. A device of the typespecified, having a wall against which aplurality of t 0 members are adapted to be clamped, mov gle jawsassociated with said wall, means adapted to actuate said jaws to clampthe type members, an additional clamping member adapted to be forcedagainst said type members in a direction erpendicular to said wall, atleast one end 0% said additional .clamping member projecting beyond theadjacent jaw, and means adapted to actuate said additional clampingmember, the end of saidadditional clamping member which projects beyondthe adjacent jaw extending through an opening in said adjacent jaw.

2.
